Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.02123 |
| Opus 5 | $0.00015 | $0.01061 |
| Sonnet 5 | $0.00006 | $0.00425 |
| Haiku 4.5 | $0.00003 | $0.00212 |
Grade A, and why
add-slack scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Via API: `curl -s -H "Authorization: Bearer $SLACK_BOT_TOKEN" "https://slack.com/api/conversations.list" | jq '.channels[] | {id, name}'` This is a copy
94% identical to add-slack — 18 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Add Slack Channel
This skill adds Slack support to NanoClaw using the skills engine for deterministic code changes, then walks through interactive setup.
Phase 1: Pre-flight
Check if already applied
Read .nanoclaw/state.yaml. If slack is in applied_skills, skip to Phase 3 (Setup). The code changes are already in place.
Ask the user
-
Mode: Replace WhatsApp or add alongside it?
- Replace → will set
SLACK_ONLY=true - Alongside → both channels active (default)
- Replace → will set
-
Do they already have a Slack app configured? If yes, collect the Bot Token and App Token now. If no, we'll create one in Phase 3.
Phase 2: Apply Code Changes
Run the skills engine to apply this skill's code package. The package files are in this directory alongside this SKILL.md.
Initialize skills system (if needed)
If .nanoclaw/ directory doesn't exist yet:
npx tsx scripts/apply-skill.ts --init
Or call initSkillsSystem() from skills-engine/migrate.ts.
Apply the skill
npx tsx scripts/apply-skill.ts .claude/skills/add-slack
This deterministically:
- Adds
src/channels/slack.ts(SlackChannel class implementing Channel interface) - Adds
src/channels/slack.test.ts(46 unit tests) - Three-way merges Slack support into
src/index.ts(multi-channel support, conditional channel creation) - Three-way merges Slack config into
src/config.ts(SLACK_ONLY export) - Three-way merges updated routing tests into
src/routing.test.ts - Installs the
@slack/boltnpm dependency - Updates
.env.examplewithSLACK_BOT_TOKEN,SLACK_APP_TOKEN, andSLACK_ONLY - Records the application in
.nanoclaw/state.yaml
If the apply reports merge conflicts, read the intent files:
modify/src/index.ts.intent.md— what changed and invariants for index.tsmodify/src/config.ts.intent.md— what changed for config.tsmodify/src/routing.test.ts.intent.md— what changed for routing tests
Validate code changes
npm test
npm run build

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-slack is a skill published in the GitHub repository mihaipora/zorya (5 stars, last pushed 6mo ago), licensed MIT. It adds 29 tokens to every session and 2,123 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 94% identical to add-slack, differing in 18 lines, and is treated as a copy.
